Participatory mapping and unmanned aerial vehicle (UAV) images for developing village level coastal geoinformation

Village maps can provide geospatial data and information that would enable them to become an important instrument in regional development planning. The purpose of this study was to produce geospatial data and information on coastal village resources based on the Indonesian Geographic Information Agency (BIG) reference guidelines. The study was conducted in Langnga Village, Mattiro Sompe District, Pinrang Regency, South Sulawesi Province, Indonesia. This research used raster and vector data. Raster data consisted of high-resolution images obtained from Unmanned Areal Vehicles. The ground truthing used open access applications and interviews with the community. The licensed Arc.GIS 10.5 software was used for the spatial analysis. The dominant land cover/land use categories were aquaculture ponds and rice fields. These areas have historically undergone a dynamic change of land use from rice fields to ponds and back again. Other land uses were settlements inhabited by farmers and fishermen. White sand beaches are one potential resource in this villages, but they are prone to abrasion. The spatial information contained in the village resource and boundary map can be considered as a breakthrough step and could become a pilot for other villages to follow.
